1 Claim. (Cl. 240-98) This invention relates to lighting and moreparticularly pertains to lamps of the type which has a translucentchimney surrounding the light producing means.

The invention provides glass chimney supporting devices for use withelectric or oil lamps which are capable of mounting a plurality ofdifferent sizes of chimneys rather than only a single size as has beencustomary heretofore. These supporting devices are simple and eifectivefor the intended purpose and are economical to produce.

The invention will be understood from the following description whenconsidered in connection with the accompanying drawings forming a partthereof, and in which:

Fig. 1 is a perspective view showing a lamp having chimney supportingdevice embodying the invention;

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1, but on anenlarged scale, and

Fig. 3 is a perspective view of the chimney supporting device shown inFigs. 1 and 2.

Like characters of reference designate the same or similar partsthroughout the several views.

Referring to the drawings and particularly to Figs. 1 to 3, the chimneysupporting device embodying the invention, is illustrated as applieddirectly to an electric light socket. A vase 42, providing the base ofthe lamp, has an electric light socket 43 aflixed in the neck of thevase by any suitable means which includes the cap 44. The socket switchis actuated by a thumb turn 45 and an electric light bulb 46 is threadedinto the socket. The chimney supporting device includes a ring 47 havinga central threaded portion 48 which is screwed on the upper end of thesocket 43 as shown in Fig. 2, and a plurality of supporting brackets 49,four as shown, equidistantly spaced about, and secured to, the ring 47.Each bracket 49 is substantially U-shaped, with legs 50 and 51 and aconnecting portion 52. The upper end of leg 50 has a laterally extendingflange 53 which is secured to the upper face of the ring 47 by anysuitable means, such as spot welding, brazing, or the like, and servesto attach the bracket to the ring. Leg 51 and base 52 have a finger 54struck out of the central parts thereof, and this finger is bentupwardly from the base 52 to a position between the two legs 50 and 51.The upper end per- 'ice tions of leg 51 and finger 54 are curved inopposite directions, and the upper end portion of leg 51 is providedwith apertures 55. The brackets 49 preferably are made of resilientmetal, and the legs 51 and fingers 54 are inclined toward each other, asshown, to provide a firmer grip on the chimney with which they come incontact. A chimney 56 of large size is engaged by the inner surfaces ofthe legs 51 of the brackets 49, and a chimney of intermediate size,indicated at 57, is engaged by the inner surfaces of the fingers 54. Atthe right of Fig. 2, the positions of the lower ends of the chimneyswith respect to the legs 51 and fingers 54 is shown, prior to thechimneys being moved downwardly into the brackets.

Obviously, in any instance where a chimney is engaged by the chimneysupporting device on the inside or the outside of the chimney, thechimney engaging means can be disposed to contact the chimney on theopposite side of the chimney without departing from the invention.

It will be understood that a preferred form of the invention has beenselected for illustration and description, but that changes can be madein the form, location and relative arrangement of the several parts ofthe form without departing from the principles of the invention, inconsequence of which the invention is not to be limited excepting by thescope of the appended claim.

What is claimed is:

An adapter for a lamp having an electric light socket, a lamp bulb inthe socket, and a translucent chimney sur rounding the bulb, comprisinga ring, a series of U- shaped supporting brackets fastened to said ring,each supporting bracket having a flange attached to said ring and bentdownwardly at approximately right angles to said ring to form one leg ofthe U-shaped supporting bracket, the other leg of said U-shapedsupporting bracket being bent upward in substantially parallel relationto said first leg to engage a chimney to be placed around said bulb byengaging said chimney on its outside, and fingers formed out of saidsecond leg and out of part of the base of the connecting U-portion ofsaid U-shaped supporting bracket and being bent backward and upward toform a resilient element to engage a chimney of another size when used,whereby chimneys of difierent sizes can be used and be engaged by eitherof said second legs or by said fingers.
